Overview

Our integrated circuits and reference designs help you create Bluetooth® headset/headphone and earbud designs, including true wireless systems (TWS) and smart headphones/hearables. Create next-generation devices that deliver premium audio with noise cancellation, ultra-low standby power and biosensing capabilities that allow you to monitor heart rate and temperature.

Design requirements:

Headsets/headphones and earbud systems often require:

  • Compact battery management with ultra-low standby for longer battery runtime.
  • Ultra-small power components with small bill of material (BOM) size, high efficiency and low standby power.
  • Biosensing to monitor heart rate and temperature during normal use or physical activity.
